LINCOLN I-IOWARD, OF SAVANNAH, MISSOURI.-

HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 704,331, dated July 8,1902.

Application tiled February 27.1902. Serial No. 95.845. (No model.)

T0 0U w/tonz/ it may concern:

Beit known that l, LINCOLN HOWARD, a citizen of the United States,residing at Savannah, in the county of Andrew and State of Missouri,have invented certain new and useful Improvements in Heating-Stoves;vand I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My object is to provide a heating-stove that will produce a greater'degree of heat with a given quantity of fuel and distribute the same YIn the drawings, A represents the drum ofthe stove, and B anfinvertedconicalbase. The top of the stove is provided with alid C, which affordsaccess to the interior for supplying the cast-iron vertically-corrugatedfirepot E with fuel.

I) is the ash-pit, provided with door d, hinged at the bottom, and a'damper D is above the ash-pit door in the cast-iron pouch. The interiorof the drum of the stove is provided with a hot-air space F betweenlining H, preferably corrugated, and the casing, and the corrugatedinverted conical base of the stove is furnished with a similarsomewhatwider hot-air space F between the corrugated fire-pot E and thecasing.

I is acorrugated iron door fittingin closely against the casing, thecorrugations leaving air-spaces F" F between said floor and the bottomcasing. J is the stove-grate, and J is the diaphragm check draft,rigidly attached to the side of the drum of the stove and provided withcircularopeningsjj. The top of the corrugated lire-pot is provided witha lateral flange L, formed by the top edge being cast outward across thetop of the narrow hot-air space F until it fits closely with `thecasing, thus entirely closing said hot-air space at its top,except atthe rear of the stove, where six, more or less, circular or V-shapedopenings M M are out out of said lateral liange between the furrows ofthe corrugations, as shown in Fig. l.

O is a fuel-support piece, preferably cast-' iron, depressed through itscenter, its front end being adapted to fit down closely around the backof the grate, while its elevated back end rests againsty the corrugatedfire-pot below the iire-pot flange. The sides and back of saidfuel-support are scalloped, so that it fits closely into the ridges 7L hand valleys h 7L ofthe corrugations of fire-pot E, thus adaptingit tofit closely and securely in the fire-pot. By the use of this fuelsupportwhen the stove is constructed in oval shape thecoal's in the nre-pot arebedded up forwardinto smaller space, and the air-space at the bottom ofthe -back of the stove is enlarged. This air-space is further enlargedby shortening the corrugated fire-pot at the back partas shown in Fig.2, thus consolidating that which would otherwise be the the lower partofthe hot-air space F at the back of the stove with the air-space beneaththe grate and beneath and back of the fuelsupport. By this constructiona free draft is made possible between the damper and the reardraft-openings M M in lateral flange L.

In the manufacture of round stoves I reserve to myself the right todispense with fuel-support O as well as the shortening of the backsection of the corrugated fire-pot.

From the foregoing description it will readily be seen that of the coldair entering the stove through the damper at the front a part will passup through the grate, while a large part will be drawn back through theash-pit into the large air-space below fuel-support O, where it will begreatly heated by the intense heat of this support and will be drawnbetween the fire-pot and the casing of the inverted conical base of thestove'up lthrough openings M IWI in the flange of the fire-pot andthence into the combustion-chamber immediately above the re, where itwill mix with the gases cooked out of the bed of coals, making a perfectcombustion, thus giving off intense heat, while the bed of coals is butslightly consumed, economizing largely in fuel and rendering the stovecomparatively smokeless.

What I claim, and desire to secure by Letters Patent, is-

l. In a heating-stove the combination of an inverted conical casinginclosing a combustion-chamber, a corrugated lioor, said corrugationsforming air-spaces between said iioor and the bottom of the casing, averticallycorrugated re-pot supported by said iioor, a fuel-support itsfront end contacting with the rear of the stove-grate and its elevatedback end with the rear of the fire-pot, a lateral flange at the top ofsaid fire-pot adapted to tit closely around against the stove-casing andprovided with semicircular openings in that portion contacting with ltherear part of the stove-casing to serve as draft-vents from beneath thecombustion-chamber under the grate and fuel support up between thecorrugations at the back of the lire-pot and the lstove-casing into thespace above the fuelbed, substantially as described and for the purposespecified.

2. In a heating-stove the combination with an inverted conicalcombustion-chamber and a vertically-corrugated tire-pot open at thelower part of the back thereof and located within said chamber andspaced therefrom to form a heating-chamber, of a fuel-support set backof the stove-grate and elevated at its rear end thereby forming anenlarged upward extension of an 'air-chamber, of a corrugated lioorbeneath the fire-pot, spaced therefrom allowing said air-chamber toextend through the entire base of the stove, of a flange on the top ofthe corrugated Jdre-pot provided at the rear of the stove with openingsadapted to carry the draft of the stove up from said air-chamber and itsupward extension into the chamber above the fuel-bed to form perfectcombustion with the gas therein, substantially as described and shown.

3. In a heating-stove comprising in combination a combustion chamber, aheatingdrum supported thereon and a perforated check-damper thereinspanning that portion adjacent to the iiue connection, averticallycorrugated fire-pot having its lower rear portion cut away, agrate set therein at the front, a fuel-support extending backward fromsaid grate and bearing upward at an angle with its edge adapted to fitinto the side and back corrugations of the fire-pot and close theopening made in the fire-pot at the cut-away portion thereof, and alateral flange on the rim of the fire-pot above said cut-away portionprovided with draft-openings at the tops of corrugations, substantiallyas set forth and shown.

In testimony whereof I ax my signature in presence of two witnesses.
